Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for low-dropout regulator (LDO) layouts, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.
To ensure stability, the output capacitor should meet the minimum ESR (Equivalent Series Resistance) and capacitance requirements specified in the datasheet. Additionally, the capacitor should be placed close to the device and the output voltage should be decoupled with a ceramic capacitor.
The maximum input voltage that can be applied to the TPS75101QPWPR is 15V, but it's recommended to operate the device within the specified input voltage range (2.7V to 12V) for optimal performance and reliability.
The TPS75101QPWPR has a soft-start feature that helps to reduce inrush current during power-up. During power-down, the device will shut down and the output voltage will decay rapidly. It's recommended to follow a controlled power-up and power-down sequence to ensure reliable operation.
The thermal derating of the TPS75101QPWPR is specified in the datasheet, but it's generally recommended to derate the device's power dissipation by 1.5°C/W above 25°C to ensure reliable operation.
